Kaynağa göre önem derecesi
Trivy'nin kendi etiketi CRITICAL. Kritik diyenler: NVD. Daha düşük diyenler: Red Hat (yüksek), Oracle (yüksek).
Açıklama
In all versions of libyang before 1.0-r5, a stack-based buffer overflow was discovered in the way libyang parses YANG files with a leaf of type "identityref". An application that uses libyang to parse untrusted YANG files may be vulnerable to this flaw, which would allow an attacker to cause a denial of service or possibly gain code execution.
